Turkey: Erdemir Group has ordered new INBA slag granulations systems as part of an order for two new blast furnaces (BF) from Luxembourg’s Paul Wurth for its Ereğli and Iskenderun integrated steel plants. At both sites a new furnace will replace an older production unit. The new blast furnaces are scheduled for blow-in in March 2021 and May 2021 respectively. No value for the order has been disclosed.

At Ereğli Erdemir’s new BF2 will have a hearth diameter of 10m, 24 tuyeres and two tapholes. It will produce 5000t/day of hot metal from an inner volume of 2188m³. At Isdemir the new BF1 will be sized at 12.5m in the hearth and 3587m³ of inner volume; it will be fitted with 32 tuyeres and four tapholes and will produce 7900t/day, which further increases the hot metal capacity at this site.

Paul Wurth will execute both projects on an EP basis including the supply of technological key items and related supervision of erection and commissioning. The orders include basic engineering of the blast furnaces with profile, cooling and lining concepts as well as the design of the stockhouses, top gas cleaning plants, slag granulation plants and BF cooling units.

For both furnaces, Paul Wurth will supply Bell Less Top charging systems and bleeder valves, refractories for the hot blast mains and bustle pipes, tuyere stocks with tuyere phenomena detection system (TPDS), technological and critical items for the top gas cleaning plants (consisting of axial cyclones, annular gap scrubbers) as well as for in total three INBA slag granulations systems. Extensive sets of TMT probes and process recorders include, inter alia, 3D TopScanburden surface profile meters and SOMA acoustic top gas temperature measurement. Under the same contracts, TMT will also supply fully hydraulic taphole machinery for equipping all the six tapholes in total.

UAE: Emirates Steel has signed a deal with Finland’s Ecofer for slag management services for 10 years from 2020. Ecofer will process slag from Emirates Steel's Abu Dhabi plant and sell it to the construction industry, according to the Khaleej Times newspaper. The steel producer has been recycling its Electric Arc Furnace (EAF) slag product since 2014, producing roughly 2.8Mt of EAF slag in this period.

"As one of the largest integrated manufacturers of finished steel products in the region, we produce 0.8Mt/yr of slag and we are committed to finding ways to mitigate our impact on the environment,” said Saeed Ghumran Al Remeithi, the chief executive officer (CEO) of Emirates Steel.

Ecofer arranged an agreement with Egypt’s Ezz Steel earlier in 2019. The latest deal with Emirates Steel continues its intent to build strategic partnerships in the Middle East.

US: Councillors at the Vallejo City Council in California are preparing to make a decision on Orcem Americas’ slag cement plant project at the end of May 2019. The council has released a new draft Final Environmental Impact Report (FEIR), according to the Vallejo Times-Herald newspaper. However, staff said the document is not ready to be presented to the council for certification and possible project approval under the California Environmental Quality Act (CEQA) due to a lack of information and cooperation from the applicants for the draft status of the report. Planning permission for the slag grinding plant and marine terminal was refused in early 2017.

India: JSW Steel has signed a 10-year agreement with US-based Harsco for a range of mill services. Harsco will provide JSW Dolvi in Maharashtra with on-site slag handling services including under-furnace digging, ladle wrecking, and hot slag transport. No value for the contract has been disclosed.

US: Charah has opened a slag grinding plant at the Port of Coeymans near Albany, New York. The unit uses the company’s proprietary process to grind granulated blast furnace slag (GBFS) to create supplementary cementitious materials (SCMs). The site is accessible by ship, truck and rail and will sell materials to concrete producers in the northeast of the country.

The new plant will also produce slag cement that is marketed under the MultiCem brand. Slag cement will be distributed throughout Charah Solutions’ MultiSource materials network, a nationwide distribution system of more than 30 sourcing locations that provide ready mix concrete (RMX) producers and other customers SCMs, including fly ash and slag cement.

US: Xavier Becerra, the attorney general of California, has warned that Orcem Americas’ proposed slag cement plant in Vallejo breaks state environmental laws. In a letter to Vallejo's planning and development services co-ordinator he said that the project would violate the California Environmental Quality Act, according to the Irish Times newspaper. Becerra also raised issues with nitrogen oxide and CO₂ emissions. The intervention is an unusual move, as the state's attorney generals do not normally intervene in planning disputes.

Orcem Americas’ chief executive officer (CEO) Stephen Bryant said that a new environmental impact report would be prepared to address Becerra’s concernsd by the end of November 2018. The company, a subsidiary of Ireland’s Ecocem, is proposing to build and operate a US$50m slag grinding plant in Vallejo. However, the project has faced opposition from local environmental groups.
